In addition to introducing Coldplay, Prince Harry spoke about his experiences in Lesotho and how he is inspired by the people he meets saying, "We must follow the example of the young people of Lesotho, and meet one of the great challenges of our generation with optimism, energy, and openness. That's what tonight is all about. When people come together for a purpose we can achieve extraordinary things."

Prince Harry and Prince Seeiso of Lesotho, who founded Sentebale together, enjoyed the concert side by side. Prince Seeiso honored his co-founder in his speech saying, "May I pay tribute to my co conspirator Prince Harry. He has become a brother and a friend and in the true African tradition has been given a Basotho name of Mohale. It means a warrior. To you my dear friend and brother Harry I wish to pay a very special tribute. You came to Lesotho as a young man and today you stand tall and proud and are walking among the giants."
He continued: "You are making a difference. That is a testimony to the mother that we so love, that is Princess Diana. You in her footsteps have gone beyond the call of duty and gone to those dark corners and reached out your hand to the most vulnerable children of Africa and in particular Lesotho."

The teen also gave Princess Charlotte's uncle a framed set of three photographs of himself as a child. Harry, clearly moved by the gift, said “Oh sweet! Look at that. Look how small you were. Is the tree still there? Do you remember the little pear tree?”
Back in 2004, the royal and Mutsu were photographed planting a tree together at the children's center where they met. Harry said, "You still look the same, just a bit taller."

Talking to HELLO! about the choir, Joss said, "They're doing really well and they seem to have got it down before I got here. I added one thing and honed in on a few bits and bobs, but they were fine. They are doing two songs from Lesotho, which are amazing and I'll sing with them. When it’s on your doorstep it's much more emotional and has a bigger effect – it will be harder to forget about."

The Sentebale Concert on June 28 will raise funds to support the charity's work helping vulnerable young people in Lesotho, including funding Sentebale's monthly Saturday Clubs and Mamohato Children's Centre, which delivers psychosocial support to children living with HIV in Lesotho and Botswana.
It will also shine a spotlight on the challenges facing charities like Sentebale that are trying to support young people living with HIV, in addition to the stigma, discrimination and a lack of education surrounding HIV/AIDs, which is still the number one cause of death in 10 to 19 year olds in Africa.
